The IISEE has started a project to determine
the following earthquake information for recent large (Mw≧7.2)
earthquakes in the world by the analytical techniques
developed by the IISEE staff members and visiting researchers.

Aftershocks
including mainshock and foreshocks are relocated
using P-wave arrivals from International Seismological Centre (ISC) CD-ROMs.
Then, the corresponding fault plane is determined based on the obtained
aftershock distribution (nodal planes are taken from the Global CMT catalog).

●We analyzed large (M≧7)
events that occurred between 1976 and 2007 to determine their aftershock
distributions and corresponding fault planes to expand the database (under
adjustment. Thank you for your patience).
